--- Comment #1 from H.J. Lu <hjl.tools at gmail dot com> ---
We do it for MacOS:
#if TARGET_MACHO
/* Output the Mach-O "canonical" pic base label name ("Lxx$pb") here.
This is what will be referenced by the Mach-O PIC subsystem. */
if (machopic_should_output_picbase_label () || !label)
ASM_OUTPUT_LABEL (asm_out_file, MACHOPIC_FUNCTION_BASE_NAME);
/* When we are restoring the pic base at the site of a nonlocal label,
and we decided to emit the pic base above, we will still output a
local label used for calculating the correction offset (even though
the offset will be 0 in that case). */
if (label)
targetm.asm_out.internal_label (asm_out_file, "L",
CODE_LABEL_NUMBER (label));
#endif
.text
.align 4,0x90
.globl _get_foo
_get_foo:
LFB0:
call ___x86.get_pc_thunk.ax
L1$pb:
movl L_foo$non_lazy_ptr-L1$pb(%eax), %eax
ret
LFE0:
.section __TEXT,__textcoal_nt,coalesced,pure_instructions
We should do something similar for Linux.
